摘要
在张弦桁架分阶段形态优化基础上,拉索内力的优化采用基于模糊逻辑的多目标遗传算法确定,并对该方法所得优化结果及影响预应力的因素进行了分析,为张弦桁架设计及预应力施工提供了一定的参考依据。
On the basis of divided-phase shape-state analytical of optimization designed truss string structure, force of cable determined by multi-object genetic algorithm based on fuzzy logic method, the results and the factors of influencing prestress are studied, which may be a reference for designing truss string structure and prestress stretching construction.
